Reflection: Conducting Crayfish Experiments - Section 1: Planning


There was some disagreement among tables when I originally asked them what crayfish sense they would like to find out more about, and they questions they developed were not quite ready for testing.  I wrote each sense on an index card, and called students up one by one while they were working on another assignment, and asked them which crayfish sense they wanted to explore.  I wrote their name on the back of the card so they couldn't pick by who was in the group, only by interest.  Once I had 5 in a group, I pulled that card out as an option.

Differentiating by allowing student choice (even if it's between only two topics) creates buy in.  It acknowledges that their interests are important, and eliminates a great deal of "Well, I wanted to to ____ but _____ said no."
